Background

Chen Xin was the Seven Treasure Glazed Tile Sect's foremost guardian and its sharpest weapon. As a rank 96 Peak Douluo, he spent his life pursuing swordsmanship and believed his attainment was unmatched on Douluo Continent. His pure sword intent and fearsome reputation had helped secure the sect's position against hostile forces. 23 38

Before becoming an explorer, Chen Xin's understanding of the sword was repeatedly challenged by the Sky Screen. He recognized the white-robed swordsmen's remote sword control as sword control through qi, a legendary art entirely distinct from Soul Power, and later became captivated by flying-sword formations beyond anything sword martial souls could achieve on Douluo Continent. 5 31

The revelation that the Yankang Imperial Preceptor was considered the greatest swordsman beneath the gods ignited Chen Xin's competitive spirit. When selected by the Sky Screen as an explorer, he left the Seven Treasure Glazed Tile Sect determined to witness this unfamiliar sword path for himself. 23 37

Appearance

Chen Xin is an elderly swordsman who nevertheless carries himself with the steadiness and sharpness of an unsheathed blade.

• White hair “like snow.” 37
• White-haired and bearded, with a gaunt frame after entering the Spirit Fetus Realm. 46
• Usually dressed in white before serving in Yankang. 37
• Carries the composure of a veteran warrior, though his posture falters when his Dao heart collapses. 38
• His aged body regains vitality after awakening his Spirit Fetus; new skin grows on his hands and his gray-white hair regains some black luster. 41
• After developing his flying-sword path, he can descend while standing upon a flying sword, surrounded by a naturally formed domain of sword intent. 66

Personality

Chen Xin is wholly devoted to the sword. His pride in the Seven Kill Sword and in his own lifelong practice is immense, but it is rooted in genuine discipline rather than empty arrogance. Even when he believes the Imperial Preceptor may kill him, he chooses to draw his sword rather than surrender his courage as a swordsman. 37 38

His defining strength is his willingness to discard what he once held sacred when confronted with a higher truth. After recognizing that the soul-ring system limits his potential, he willingly sacrifices rank 97 power to begin again in Yankang's cultivation system. 39 41

• Values real skill over rank, status, or appearances. 46
• Treats superior understanding with humility; he kneels to thank the Imperial Preceptor after his breakthrough. 39
• Seeks to learn from unfamiliar systems rather than reject them. 40
• Remains composed under insult after losing his former power, including when Niu Niu mocks him. 42
• Regards the integration of cultivation into ordinary work as broader and more meaningful than Douluo's soul-master culture. 42
• Treats defeat as proof of insufficient knowledge rather than a blow to his pride, immediately seeking Mo Wufeng's instruction after losing their duel. 67
• Is fiercely loyal to Yankang after it gives him refuge and access to a new sword path; he refuses Mo Wufeng's offer to become the Heavenly Saint Sect Sword Hall's Deputy Hall Master. 67

Abilities & Skills

Sword Intent

Chen Xin possesses an exceptionally pure killing sword intent, refined through more than ninety years of sword practice. The Yankang Imperial Preceptor identifies it as a will that abandons complex variation and exists purely for slaughter. 39

• His intent remains intact after the destruction of his martial soul, soul rings, and soul power. 41
• It enables him to perceive and exploit minute weaknesses in opponents. 42
• It is valued by the Imperial Preceptor as material that can improve Yankang sword techniques. 39
• A trace of Su Muzhe's Sword Intent enters Chen Xin's brow and reinforces both his Spirit Fetus and its miniature sword. 45
• His later sword intent is powerful enough to form a sword domain around him and to compress into an invisible flying sword. 66 67

Seven Kill Sword Technique

Before abandoning the soul-ring system, Chen Xin wielded the Seven Kill Sword and was known for having the greatest attack power among Douluo's swordsmen. 37

• Ninth Soul Skill: God and Demon Slash — Condenses his essence, qi, spirit, and killing intent into a massive, direct sword strike. 39
• The Imperial Preceptor disperses God and Demon Slash by tapping its structural node with two fingers, exposing the rigidity of Chen Xin's former sword path. 39
• The technique is lost when Chen Xin destroys his martial soul and nine soul rings. 41

Arithmetic-Infused Swordsmanship

After studying Yankang's teachings, Chen Xin incorporates arithmetic, formation principles, wind conditions, spatial curvature, vital-energy flow, and an opponent's physical movements into his swordplay. 40 46

• Calculates openings, trajectories, and structural weak points rather than relying solely on force. 37 46
• Uses a willow switch to defeat Zhao Rui, a Five Luminaries Divine Treasury cultivator, despite having only newly awakened Spirit Fetus cultivation. 46
• Defeats Hidden Sword Pavilion cultivator Lin Feng, demonstrating the effectiveness of Yankang's arithmetic-based sword system. 48
• Requires continued study; Chen Xin considers himself to be rebuilding his swordsmanship from its foundation. 40 43
• Progresses to the use of microscopic formations, geometry, spatial curvature, and calculus-based variables in his sword arts. 66 67
• Identifies the core formation node of Mo Wufeng's three-hundred-and-sixty-sword dragon, though he is ultimately defeated when its topology transforms into a sealed Möbius-like spatial loop. 67

Spirit Fetus Cultivation

Chen Xin begins cultivating Yankang's Divine Treasury system after his original soul-ring system is removed. 41

• Awakens his Spirit Fetus by using breathing techniques to draw spiritual qi into the point between his brows. 41
• Gains vital energy that is more condensed and sharper than his former soul power, though initially far less vast. 41
• His new body is physically vulnerable compared with his former rank 97 state. 42
• Uses only physical strength, vital energy, and sword intent in his early battles in Yankang. 42
• His golden Spirit Fetus becomes more solid after absorbing Su Muzhe's residual Sword Intent. 45

Flying-Sword Formations

After continuing his arithmetic studies, Chen Xin develops a flying-sword path independent of his former Seven Kill Sword martial soul. 66 67

• Commands ten tangible flying swords engraved with microscopic array patterns and can use a flying sword as a mount. 66 67
• Interweaves the physical swords into a microscopic sword diagram through precise formation calculations. 67
• Condenses an invisible eleventh flying sword from ultimate sword intent and tens of thousands of calculus formations; its sharpness creates a vacuum in the surrounding space. 67
• Can merge his physical flying swords into the invisible blade to perform Swords Become One—Cleave All Things, a strike designed to cut through an enemy formation's core. 67

Equipment / Weapons / Items

• Seven Kill Sword — Chen Xin's former martial soul and sword; lost when he destroys his martial soul and soul rings. 37 41
• Wunian — A sword forged from Taibai Divine Gold and Chen Xin's sword intent. Its name means “no thoughts, no desires—only the sword.” 47
• Flying-sword set — A set of tangible flying swords inscribed with microscopic array formations, developed during Chen Xin's continued study of arithmetic-based swordsmanship. 66 67
• Divine Strategy Battalion instructor token — Bronze tiger-head waist token confirming his appointment as an instructor. 46
• Library Pavilion token — A token from a mysterious white-robed young master that grants Chen Xin access to all nine floors of the Imperial Academy Library Pavilion. 44
• Willow switch — Used to defeat Zhao Rui during his first demonstration as an instructor. 46

Relationships

• Ning Fengzhi — Sect master of the Seven Treasure Glazed Tile Sect; regards Chen Xin as family and relies on him as one of the sect's essential protectors. 37 38
• Gu Rong — Fellow Titled Douluo and elder of the Seven Treasure Glazed Tile Sect; worries with Ning Fengzhi when Chen Xin's Dao heart collapses. 38
• Yankang Imperial Preceptor — Mentor and fellow Daoist; heals Chen Xin, guides his breakthrough to rank 97, helps him discard the soul-ring system, and recognizes the value of his killing sword intent. 39 41
• Emperor Yanfeng — Yankang's emperor; recruits Chen Xin as swordsmanship instructor for the Divine Strategy Battalion and supports the forging of Wunian. Chen Xin later regards Yankang's acceptance and support as a debt of loyalty. 41 46 47 67
• Bashan Libationer — Tests Chen Xin's foundation after his rebirth, respects his resolve, and offers to teach him Yankang combat techniques and Arithmetic blueprints. 42 43
• Zhao Rui — Deputy commander of the Divine Strategy Battalion; initially doubts Chen Xin, then acknowledges him as instructor after losing their duel. 46
• Lin Feng — Hidden Sword Pavilion cultivator defeated by Chen Xin in a sword duel. 47 48
• Su Muzhe — Legendary sword god whose surviving sword intent and writings deepen Chen Xin's understanding of the sword path. 44 45
• Yang Wudi — A fellow Douluo cultivator whose encounter with Chen Xin's reborn flying-sword path inspires him to pursue the Heavenly Saint Sect's arithmetic teachings. 66 67
• Mo Wufeng — Heavenly Saint Sect Sword Hall Master who defeats Chen Xin with superior formation mathematics, praises his talent, and offers to personally teach him. Chen Xin declines formal recruitment but accepts the prospect of future exchanges on swordsmanship and mathematics. 67

Story Role / Major Arcs

Arrival in Yankang

Chen Xin arrives in Yankang's capital and is immediately struck by its dense vital energy and the way ordinary citizens use cultivation in daily life. Realizing that his rank 96 bottleneck has begun to loosen, he seeks out the Imperial Preceptor's public sword lecture at the Imperial Academy. 37

Collapse and Reconstruction of His Sword Heart

The Imperial Preceptor's teaching—that swordsmanship must account for mathematics, space, natural laws, wind, light, and vital-energy movement—shatters Chen Xin's faith in his former methods. He coughs blood as his Dao heart collapses, but the Preceptor heals him rather than treating him as an enemy. 37 38 39

Chen Xin attacks with God and Demon Slash at the Preceptor's invitation. After seeing the technique neutralized at its weakest node, he comprehends a broader sword path, reaches rank 97, and accepts the Preceptor as a teacher in all but name. 39

Service to Yankang and Rebirth

Chen Xin agrees to serve Yankang, meets Emperor Yanfeng, and is appointed swordsmanship instructor of the Divine Strategy Battalion. Seeking to escape the limitations of the soul-ring system, he requests that the Imperial Preceptor destroy his martial soul, nine soul rings, and all soul power. 40 41

He survives the process and awakens his Spirit Fetus, beginning again as a cultivator of Yankang's Divine Treasury system. 41

New Sword Path

At the Imperial Academy, Chen Xin accepts Bashan Libationer's test and demonstrates that his sword intent and calculated perception remain dangerous even without soul power. 42

He studies arithmetic and formation theory, gains access to the Library Pavilion's ninth floor, and encounters the sword intent left by Su Muzhe. Inspired by Su Muzhe's example, Chen Xin resolves to pursue a sword path that can reach heaven and confront the gods. 44 45

As the Divine Strategy Battalion's instructor, he defeats Zhao Rui with a willow switch by applying arithmetic to combat. Emperor Yanfeng subsequently has the sword Wunian forged specifically for him. 46 47

Flying-Sword Rebirth and Sword Hall Challenge

Following further study of arithmetic and microscopic formations, Chen Xin develops a formation-based flying-sword art and appears before Yang Wudi with a new set of flying swords. His sword path has advanced far beyond the fixed soul skills and martial soul he once relied upon. 66 67

Chen Xin challenges Heavenly Saint Sect Sword Hall Master Mo Wufeng to test this new path. Although his invisible flying sword can identify and strike the core of Mo Wufeng's sword-dragon formation, Mo Wufeng's superior mathematical understanding traps and breaks Chen Xin's attack within a topological sword formation. 67

Rather than becoming discouraged, Chen Xin asks to understand the mathematical principle behind his defeat. He declines Mo Wufeng's offer of the Sword Hall Deputy Hall Master position, declaring his loyalty to Yankang while leaving open the possibility of future scholarly exchanges. 67

Imperial Assassination Crisis

When five Divine Bridge Realm assassins ambush Emperor Yanfeng, Chen Xin is overwhelmed by the gulf between his own strength and that of the attackers. The crisis further reveals the vastness of Yankang's cultivation system when Emperor Yanfeng defeats the five assassins through his own peak Divine Bridge Realm martial cultivation. 75 76 77
